This class defines a dependent Mirror curve. A Mirror curve is similar to a mirror object that you create using the Mirror tool (on the 3ds Max toolbar) or the Mirror modifier. It is the original curve reflected about one or two axes.
Any of the object's properties may be set via optional keyword arguments on the constructor.
The parent curve by NURBSet index.
The axis or axes of reflection for the curve.
This is an additional transformation applied to the axis specification. This corresponds to the gizmo the user may use interactively to alter the location of the mirror axis. This is exactly equivalent to setting the transform on the gizmo of a mirror modifier.
